Objective:To determine the acetylcholinesterase inhibitory（AChE1） and antioxidant activity of the ethyl acetate and methanol extracts of 12 traditional medicinal plants used in the treatment of neurological ***:AChEI activity was determined spectrophotometrically using the Ellman’s colorimetric *** activity was carried out by determining the ability of the extracts to scavenge 2,2-diphenyl-1-picryl hydrazyl（DPPH） and 2,2’-azinobis- 3-ethylbenzothiazoline-6-sulfonic acid（ABTS） *** levels of total phenols,flavonoids and flavonols were determined quantitatively using spectrophotometric ***:AChEI was observed to be *** schweinfurthii（***）（Engl.） *** Scadoxus puniceus（***）（l.） Friis & *** extracts showed the lowest IC50 value of 0.000 3 mg/ml for the ethyl acetate extracts while Zanthoxylum davyi（***）（***.） P.G. Watermann had the lowest IC50 value of 0.01 mg/ml for the methanol extracts in the AChEI assay. The roots of Piper capense（***） l.f.,***,Ziziphus mucronata（***） Willd.,*** and Crinum bulbispermum（***）（Burm.f.） Milne-Redh.& *** noteworthy radical scavenging activity and good AChEI ***: Five plants show good antioxidant and AChEI *** findings support the traditional use of the plants for treating neurological disorders especially where a cholinesterase mechanism and reactive oxygen species（ROS） are involved.

This research was to observe patients,who underwent orthodontic tooth alignment correction with dental brackets,for the purpose of early detection of white spots(early satge of caries)and dynamic measurement of distance between teeth edges based on the digital photographs taken with a smartphone Sony Xperia *** reading was realized taking into account the adjustment of color features of a standard ceramic surface(tile)that was selected during the dental brackets installation period,the photo of which was taken simultaneously during the dynamic observation *** color scale RGB was transformed into CIE l*a*b scale of color measurement with regard to the correction of RGB components of image by usage of correction coefficient for calibration tile surface RGB *** expert appraisal showed sensitivity of proposed method was between 88.7%and 96.2%(the mean 93.1%)and specificity between 68.4%and 84.2%(the mean 75.4%).The positive predictive value was between 89.5%and94.0%(the mean 91.5%);and the negative predictive value was between 72.7%and 86.7%(the mean 80.6%).The measurement of the distance between teeth edges during the first 10 days following the brackets installation was carried out using a self-scalable ruler that was calibrated,according to the standard sizes of the dental bracket system *** Android application of self-scalable ruler was developed using *** development of a pronounced pain syndrome was observed when the velocity of distance changes between teeth edges was rather high-0.051+0.004 mm/*** improvement of efficiency of the suggested method is expected due to application of illumination standards during the shooting period.
